Disable Testing pipeline for `PA2024CH`

[AlexAxthelm]

Results are delivered to users, and no further development expected.

Disable testing pipeline for these reports to reduce GH actions usage (significantly) once we are confident that we have exhausted most user bug reports.

Relates to #392

Let's wait until next Friday.
If we reach that date with no flagged user queries (or more specifically, no user queries that result in any required change to our code), then we disable it :-)
